Overview: New vulnerabilities are discovered at a rapid rate, so in order to discover and defend against them, companies conduct vulnerability scanning. However, the frequency and coverage of scans provide increasing challenges for some organizations. Active scanning can be disruptive if conducted excessively, and there are some parts of the network that companies don't feel comfortable scanning at all. In order to address this problem, Skybox Security has introduced what it refers to as its next-generation vulnerability management product that discovers vulnerabilities without the need for an active scan.
